Title: Combined steam cracker and butene dehydrogenation light ends
IPC: C07C7/00
Filed: 1960-10-26
Abstract: <FORM:0900374/IV (b)/1> Hydrocarbons are separately recovered from the light ends from a steam cracker operated to produce olefins and diolefins and a butene dehydrogenation unit employing two or more reactors, one or more of which is in stream while one is being regenerated, by combining the two streams, compressing to above 150 p.s.i.g. and passing to an absorption/fractionation system to recover the separate components.  A naphtha or gas oil, e.g. boiling in the range 350-700 DEG F. is supplied with steam to furnace 2 operated at 1300-1500 DEG F., 0-50 p.s.i.g. with residence times of 0.05-1 second. The effluent is quenched to 400-600 DEG F. with heavy oil supplied through line 4 and passed to distillation tower 6 where tar, quench oil, and gas oil are separated from light ends recovered overhead.  These are cooled to 75-125 DEG F. and C6- materials passed to compressor 14 and heavier materials removed through line 15.  A butane/butene feed containing 70-95% mol butenes is heated in furnace 18 and contacted with catalyst in one of reactors 22 and 29, the other being on regeneration.  Using calcium nickel phosphate as catalyst the feed is mixed with steam and passed at 1,000-1,400 DEG F. into the reactor with a butene gas rate of 75-200 v/v/hr. and a steam rate of 1,400-4,000 v/v/hr. and a pressure of 15-30 p.s.i.a. Using chromia alumina the temperature may be 1,000-1,200 DEG F. at 1-15 p.s.i.a. with a WHSV of 0.5-1.5 wt./hr./wt.  On switching reactors from on stream to regeneration the effluent rate fluctuates, the fluctuation being diminished by combining with the steam cracker light ends before passing to the compressor 14.  Steam if present is condensed out in separator 33.  The combined stream cooled to 75-125 DEG F. and in separator 39 C3- are taken overhead through line 40 while heavier materials pass with material in line 15 to naphtha splitter 42 where C6+ materials are removed as bottoms while the overhead is caustic treated to remove sulphur compounds and CO2 and passed to absorber de-ethaniser 47.C3- compounds in line 40 are treated with diethanolamine for removal of H2S and CO2 in tower 48 and with a caustic wash in tower 53 before passing to absorber de-ethaniser 47.  Here the vapours are treated with a C5 lean oil obtaining a C2- stream overhead.  This is washed with sponge oil in tower 59 to remove traces of C5 lean oil. C2-product is recovered in line 60.  The C3+ material from the bottom of tower 47 is fractionated in tower 62 to obtain C5 products as bottoms, part being used as the C5 lean oil in tower 47.  The overhead is split in tower 69 into C3 overhead and C4 bottoms which latter passes to butadiene extraction.  Generally in the combined light ends the C4/C3 ratio will be 0.7-2:1 and the butene dehydrogenation effluent will be 5-50% by volume of the steam cracker light ends.  The debutaniser 62 can be operated at less than 140 p.s.i.g., i.e. lower than a conventional steam cracker debutaniser.

Abstract: 1398646 Cooling dynamoelectric machines GENERAL ELECTRIC CO 16 Aug 1973 [24 Aug 1972] 38827/73 Heading H2A [Also in Division F4] In a dynamoelectric machine, e.g. a turbine generator 11, comprising a gas-tight outer casing 12 filled with a gas coolant, e.g. hydrogen, and containing dynamoelectric machine parts, e.g. stator bars 17, which are arranged to be so liquid-cooled, e.g. by water, that during normal steady-state operating conditions the gas coolant pressure exceeds the liquid coolant pressure, and a liquid cooling system for the parts and a liquid coolant storage tank 31, there are provided means for sensing overload conditions in the machine and, co-operatively associated with such means, means for temporarily pressurizing the liquid coolant during periods of transient overload conditions the latter means including a gas supply tank 55 connectible to the liquid coolant storage tank. Thus the increased pressure of the liquid raises its boiling point and thereby increases its heat removal capability 5. The sensing means may be an operator manually controlling the pressurization upon a read out of transient overload conditions or, as shown, automatic in the form of thermocouples, 57 at the liquid coolant end of each stator winding hollow bar 17 and also a transformer 65 responsive to current overloads; these signal an actuator 59 which upon such overloads opens a valve 61 to pressurize the liquid and possibly to close both a valve 67 in a recirculating lag and a closure means 51 in a vent 49 in the storage tank 31.

Abstract: 1525537 Boring earth &c OTIS ENG CORP 22 Sept 1976 [6 Oct 1975] 39326/76 Heading E1F A hydraulic jar for imparting an upward impactive force to a well tool comprises an anvil 42 attached to a sub 48 which in use is connected to the well tool, a piston 10 attached to a sub 32 which in use is connected through a tool string to a wireline, and a tubular housing 14 movable between the subs 32, 48 and including both a cylinder portion 12 surrounding the piston 10, and a cage portion 40 surrounding the anvil 42. The cage portion 40 includes a hammer 46 for striking a shoulder 44 on the anvil 42. The anvil 42 carries collet fingers 54 which have shoulders 56 to lock against a shoulder 58 of the cage portion 40 so that the anvil 42 and hammer 46 are locked apart. A retainer collar 60 biased by a spring 62 maintains the locking of shoulders 56, 58 until a shoulder 66 on a stinger 64 is raised sufficiently to engage and lift the collar 60. The stinger 64 is connected to the piston 10 so that the lock is removed when the wireline is sufficiently tensioned to fully extend the piston, i.e. when a shoulder 68 on the head 16 of the piston 10 engages a shoulder 70 of the housing 14. Energy stored in the tensioned wireline is then released as the housing 14 accelerates upwards and the hammer 46 strikes the anvil shoulder 44. Tensioning of the wireline is achieved by providing resistance to the upward movement of the piston 10 as it is extended, this being achieved by providing a bleed passage through the piston head 16. The bleed passage comprises passages 92 through the body 34 of the piston, an annular passage 101 between a blind bore 96 in the end of the stinger 64 and the grooved outer surface 22 of a sleeve 24 and passages 98 through the stinger 64. So that the piston 10 may readily fall before repeating the jarring action, a bypass passage also passes through the piston 10. The bypass passage comprises the passages 92, the bore of the sleeve 24, this being closed by a check valve 28 when the piston is being raised, ports 102 in the sleeve 24, and the passages 98. The cylinder portion 12 containing the piston head 16 is sealed by a floating piston 74 and a seal 72. Before attachment of the sub 32, the cylinder portion 12 is filled with fluid through passage 84 which is then sealed at 86.
